Thanks for all the useful help & Info guys!!!
The Aimpoint ML2-2x is a little bigger than I initially expected. I opted for the Aimpoint QRP mount with riser (instead of the ARMS M68) and its rock solid. the front post is magnified and its a suitable stand alone optic for my purposes. Although I will still seek out a few alternate options on the BUIS (Troy are nice) but I think that I may try the Magpul MBUS.

Overall a nice optic. I think that a ARD killflash is in order (its a big piece of glass) and its larger than the standard Aimpoint.
